Scooby-Doo (character) and Shaggy Rogers win an all-expenses-paid stay at WWE City to watch WrestleMania after beating the hardest level of the organization's latest video game. At the insistence of the duo, Fred Jones (Scooby-Doo), Daphne Blake, and Velma Dinkley agree to join them on the trip to WWE City. Upon their arrival, the Mystery Machine crashes on a ditch after Fred narrowly avoids a crossing raccoon. The gang meets John Cena, his trainer Cookie, and Cookie's nephew Ruben before Cena lifts the Mystery Machine back on the road. They also encounter Bayard, a hunter who despises WWE for building their city in his forest. Cena gives the gang VIP tickets to the next event to make up for their altercation with Bayard.
